Description

Technical Field

[0001] The present invention relates to the field of medical devices, specifically an arthroscopic intravenous infusion device for orthopedic sports medicine. Background Art

[0002] With the rapid development of the fields of orthopedics and sports medicine, the demand for precision equipment in surgery is increasing day by day. As a minimally invasive treatment method, arthroscopic surgery has been widely used in the fields of orthopedics and sports medicine. During such surgeries, to ensure the smooth progress of the operation, an intravenous infusion device is used to hang saline or irrigation fluid bags to provide the liquid supply in the surgical environment. The intravenous infusion device needs to be able to flexibly adjust the height and position of the hanging water bag to meet the requirements of different surgical scenarios, and the device itself needs to have sufficient stability to ensure the safety of surgical operations.

[0003] Currently, common intravenous infusion devices mostly adopt a single gear drive or screw drive structure to achieve the height adjustment of the hanging water bag. These devices have certain limitations in actual use. For example, the height adjustment range is limited, the power transmission is not stable, or there is easy shaking during the adjustment process. In addition, the hook position of most devices is a fixed design and cannot be flexibly adjusted, making it difficult to quickly adapt to different surgical scenarios, increasing the operation burden on medical staff. Some devices also lack a reliable base fixing structure, and the positioning is not accurate enough after movement, affecting the efficiency and safety of the operation.

[0004] In the prior art, due to the single transmission method, it is difficult to meet the requirements of complex medical scenarios for the height adjustment and position adjustment of the hanging water bag. At the same time, during the long-term use of the device, transmission components such as racks and gears are prone to wear, resulting in jamming or instability when adjusting the hanging water bag. Especially during the operation, these problems will have an adverse impact on the smooth progress of the operation. Therefore, the existing intravenous infusion devices have obvious deficiencies in terms of adjustment range, stability, and durability, and there is an urgent need for a new type of intravenous infusion device that can efficiently solve these problems.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to the attached Figure 1 - attached Figure 7, an arthroscopic infusion device for orthopedic sports medicine according to an embodiment of the present invention includes an infusion rack 1. An auxiliary barb 2 is fixedly connected to the outer wall of the infusion rack 1. A fixed base 12 is fixedly connected to the bottom of the infusion rack 1. A first rotating shaft 6 is rotatably connected inside the infusion rack 1. A first gear 7 is fixedly connected to the outer wall of the first rotating shaft 6. A rack 13 is slidably connected inside the infusion rack 1. The rack 13 meshes with the first gear 7. A hanging water connection frame 10 is fixedly connected to the top of the rack 13. A hook 11 is arranged on the outer wall of the hanging water connection frame 10. A limiting component is arranged inside the infusion rack 1 for assisting in limiting the movement of the rack 13. A driving component is arranged inside the infusion rack 1 for driving the rack 13 to move; The driving component includes two driving rods 3. Both of the two driving rods 3 are rotatably connected inside the infusion rack 1. A worm 4 is fixedly connected to the outer wall of each of the two driving rods 3. A worm gear 5 is rotatably connected inside the infusion rack 1. The two worm gears 5 respectively mesh with the two worms 4; the worm 4 and the worm gear 5 are both rotatably connected inside the infusion rack 1. One end of the worm gear 5 is fixedly connected to the first rotating shaft 6. The worm 4 and the worm gear 5 are used to drive the first rotating shaft 6 to rotate.

[0024] In one embodiment, during use, first start the driving component. The worm 4 is driven to rotate by the driving rod 3. The worm 4 meshes with the worm gear 5. The rotational movement of the worm gear 5 drives the first rotating shaft 6, driving the first gear 7 fixed to its outer wall to rotate synchronously. The first gear 7 meshes with the rack 13. When the first gear 7 rotates, the rack 13 slides vertically inside the infusion rack 1. The hanging water connection frame 10 is fixedly connected to the top of the rack 13. The hanging water connection frame 10 moves synchronously with the rack 13, thereby driving the hook 11 and the hanging water bag as a whole to move up and down, realizing the adjustment of the height of the hanging water bag; through the limiting component inside the infusion rack 1, the movement of the rack 13 is effectively restricted, preventing deviation or shaking. The auxiliary wheel 9 is in sliding contact with the outer wall of the rack 13, further reducing the movement resistance and improving the smoothness. By operating the two driving rods 3, the heights of the two hooks 11 can be adjusted respectively to meet the requirements of different surgical environments; In order to accurately adjust the position of the hanging water bag on the horizontal plane, the device adopts a screw drive mechanism. A connection seat 14 is fixedly connected to the top of the hanging water connection frame 10. A limiting column 15 is arranged inside the connection seat 14. A lead screw 17 is fixedly connected inside the limiting column 15. The outer wall of the lead screw 17 is in threaded cooperation with the sliding rod 18; one end of the sliding rod 18 is fixedly connected to the hook 11, and the other end is fixed with a second limiting plate 19.

[0025] When adjusting the horizontal position of the hook 11, rotate the driving ring 16, and the driving ring 16 drives the lead screw 17 to rotate inside the limit post 15; since the lead screw 17 is threadedly connected to the sliding rod 18, the rotation of the lead screw 17 causes the sliding rod 18 to linearly slide along the limit post 15, thereby driving the hook 11 to move; the second limit plate 19 guides and limits the moving direction of the sliding rod 18 to avoid deviation or looseness and ensure the accuracy of the movement of the hook 11. Through this adjustment mechanism, the horizontal position of the hook can be adjusted according to actual needs.

[0026] The limit assembly includes a first limit plate 8, the outer wall of the first limit plate 8 is fixedly connected inside the water hanging rack 1, the outer wall of the rack 13 is slidably connected inside the first limit plate 8, and an auxiliary wheel 9 is rotatably connected to the outer wall of the first limit plate 8; the outer wall of the auxiliary wheel 9 is slidably connected to one side of the outer wall of the rack 13, and the auxiliary wheel 9 is used to assist the movement of the rack 13.

[0027] In one embodiment, the outer wall of the first limit plate 8 is fixedly connected inside the water hanging rack 1 to form a fixed track; the outer wall of the rack 13 is slidably connected to the inside of the first limit plate 8, so that the rack can only slide up and down along the track specified by the limit assembly under the drive of the drive assembly, thereby ensuring that the movement direction of the rack is accurate and does not deviate; an auxiliary wheel 9 is rotatably connected to the outer wall of the first limit plate 8, and the auxiliary wheel 9 is in contact with the outer wall of the rack 13; when the rack 13 slides up and down, the auxiliary wheel 9 rotates synchronously with the movement of the rack, thereby achieving a rolling support effect; the addition of the auxiliary wheel not only reduces the frictional resistance between the rack and the limit assembly, but also plays a further guiding role in the movement direction of the rack to ensure that the rack always maintains a stable and smooth sliding state.

[0028] A connection seat 14 is fixedly connected to the top of the water hanging connection frame 10, a limit post 15 is fixedly connected inside the connection seat 14, a driving ring 16 is rotatably connected inside the connection seat 14, a lead screw 17 is fixedly connected inside the driving ring 16, a sliding rod 18 is threadedly connected to the outer wall of the lead screw 17, one end of the sliding rod 18 is fixedly connected to the hook 11, and a second limit plate 19 is fixedly connected to the outer wall of the sliding rod 18; both the sliding rod 18 and the second limit plate 19 are slidably connected inside the limit post 15, the second limit plate 19 is used to limit and guide the movement of the sliding rod 18, and the sliding rod 18 is used to drive the hook 11 to move, and thus the position is adjusted.

[0029] In one embodiment, when it is necessary to adjust the position of the hook 11, the user operates by rotating the driving ring 16. The driving ring 16 is installed inside the connecting seat 14 and is fixedly connected to the lead screw 17. When the driving ring rotates, the lead screw 17 rotates synchronously. Since the outer wall of the lead screw 17 is threadedly connected to the sliding rod 18, the rotation of the lead screw causes the sliding rod 18 to linearly slide along the inside of the limiting column 15; one end of the sliding rod 18 is fixedly connected to the hook 11, and when the sliding rod moves, the hook adjusts its position synchronously. A second limiting plate 19 is also fixedly connected to the outer wall of the sliding rod, and the second limiting plate slidably cooperates with the inner wall of the limiting column 15 during the sliding process, thereby effectively guiding the movement direction of the sliding rod and preventing it from shifting or shaking.

[0030] A connecting column 20 is rotatably connected inside the drip rack 1. The top of the connecting column 20 is fixedly connected to a driving handwheel 21, the bottom of the connecting column 20 is fixedly connected to a threaded rod 22, the outer wall of the threaded rod 22 is threadedly connected to an I-shaped sliding seat 23, the inside of the I-shaped sliding seat 23 is slidably connected to a guiding column 24, the outer wall of the I-shaped sliding seat 23 is fixedly connected to a first toothed plate 25, the inside of the fixed base 12 is slidably connected to a second toothed plate 28, the bottom of the second toothed plate 28 is fixedly connected to a universal wheel 29, the bottom of the first toothed plate 25 is fixedly connected to a fixing plate 30, and a switching component is arranged inside the fixed base 12. The switching component is used to drive the universal wheel 29 and the fixing plate 30 to move in opposite directions; the outer wall of the I-shaped sliding seat 23 is slidably connected inside the fixed base 12, and the I-shaped sliding seat 23 is used to drive the first toothed plate 25 to slide inside the fixed base 12; both ends of the guiding column 24 are fixedly connected inside the fixed base 12, and the guiding column 24 is used to limit and guide the movement of the I-shaped sliding seat 23.

[0031] In one embodiment, during use, the user operates by rotating the driving handwheel 21. The driving handwheel 21 is fixedly connected to the top of the connecting column 20. When the handwheel is rotated, the connecting column 20 drives the threaded rod 22 to rotate synchronously; the outer wall of the threaded rod 22 is threadedly connected to the I-shaped sliding seat 23, and the rotational movement of the threaded rod is converted into the linear movement of the I-shaped sliding seat; the I-shaped sliding seat 23 slides along the inner track of the fixed base 12 under the action of the guiding column 24; the guiding column 24 provides a limiting and guiding function to ensure that the I-shaped sliding seat does not tilt or shift during the sliding process. As the I-shaped sliding seat slides, the first toothed plate 25 fixedly connected to its outer wall moves accordingly.

[0032] The switching component includes a second rotating shaft 26. A second gear 27 is fixedly connected to the outer wall of the second rotating shaft 26. The two sides of the outer wall of the second gear 27 are sequentially threadedly connected to the first toothed plate 25 and the second toothed plate 28.

[0033] In one embodiment, when the user rotates the driving handwheel 21, the handwheel drives the I-shaped sliding seat 23 to move under linear guidance through the threaded rod 22. A first toothed plate 25 is fixedly connected to the outer wall of the I-shaped sliding seat 23. When the first toothed plate 25 moves linearly, the rack portion of the first toothed plate meshes with the second gear 27, and the movement of the first toothed plate drives the second gear to rotate; both sides of the outer wall of the second gear 27 mesh with the rack portions of the first toothed plate 25 and the second toothed plate 28 respectively, and the rotation of the second gear causes the second toothed plate 28 to move in the opposite direction relative to the first toothed plate. The upward movement of the first toothed plate will cause the second toothed plate to move downward; conversely, the downward movement of the first toothed plate will cause the second toothed plate to move upward; a universal wheel 29 is fixedly connected to the bottom of the second toothed plate 28, and a fixing plate 30 is fixedly connected to the bottom of the first toothed plate 25. When the user moves the first toothed plate 25 upward by driving the handwheel 21, the second toothed plate 28 moves downward under the drive of the second gear 27, causing the universal wheel 29 to gradually retract into the fixed base 12, and the fixing plate 30 moves downward and fits the ground to complete the fixing operation of the device; conversely, when the first toothed plate 25 moves downward, the second toothed plate 28 moves upward, driving the universal wheel 29 to extend out of the fixed base 12, and the fixing plate 30 gradually retracts into the fixed base to complete the switching of the device to the moving state.

[0034] Working principle: When the arthroscopic infusion device for orthopedic sports medicine is needed, first hang the required infusion belt on the outer wall of the hook, then drive the drive rod to drive the worm to rotate inside the infusion rack, and then, in cooperation with the meshing relationship between the drive rod and the worm wheel, the worm wheel drives the first rotating shaft to rotate with the rotation of the worm, so that the first rotating shaft drives the first gear to rotate inside the first limiting plate, and then, through the meshing relationship between the first gear and the rack, the rack drives the infusion connecting frame to move linearly with the rotation of the first gear, and further drives the hook and the infusion bag to adjust the height through the infusion connecting frame. In addition, the height of the two hooks can be adjusted by driving the two drive rods respectively, so as to facilitate the separate adjustment of the two hooks according to different needs; In addition, the driving ring rotates inside the connecting seat, so as to drive the lead screw to rotate inside the limiting column through the driving ring, and then, in cooperation with the threaded relationship between the lead screw and the sliding rod and the limitation of the second limiting plate, the sliding rod drives the hook to move linearly with the rotation of the lead screw, and further drives the infusion bag to adjust the position through the hook; Finally, the driving handwheel drives the connecting column to rotate, thereby driving the threaded rod to rotate through the connecting column. With the threaded relationship between the threaded rod and the I-shaped sliding seat, and the limiting and guiding of the guiding column, the I-shaped sliding seat moves linearly as the threaded rod rotates. Then, the four tooth plates one are driven to move up and down inside the fixed base through the four top corners of the I-shaped sliding seat, thereby driving the fixed plate to move up and down. At this time, with the meshing relationship between the tooth plate one and the gear two, the gear two rotates as the tooth plate one moves. Then, through the meshing relationship between the gear two and the tooth plate two, the tooth plate two drives the universal wheel to move linearly as the gear two moves, so that the tooth plate two drives the universal wheel and the fixed plate to move in the opposite direction. When the fixed plate moves to the ground, the universal wheel can be retracted into the fixed base. If the universal wheel is attached to the ground, the fixed plate can be moved into the fixed base, thereby moving the drip stand and fixing it after the movement respectively.
